FASTENER.

Application filed March 8, 1921.

Y. To all iti/1071i t may concern lie it known that l, FRED l. CARR, a` citio't the llnited States. end e resident oit Newton. in the county oit Middlesex and Cominonweoltb oi: Ti/lfossochnsetts, have invented on Improvement in Fasteners, of which tbe Yfollowing description, in` connection with the accompanying drawings. iso speciication7 like characters on the drawings representing like parts.

This invention pertains to `iinproveinents in Frsteners lt is among' the objects oit' the invention to provide n socket for separe-ble 'fasteners in which. where relatively light gouge metal is used t'or the socket casing, the .trength oi the socket is materially 1ncreesed, and in which smoothness oi? operation ot the i'nstener is promoted.

l n the drawings. which show a preferred embmlinient ot my invention Figure l shows tWo pieces oi2 tnbric held together by :i stud and socket fastener; y

Fig'. 4f is :i :t1-ont elevation ot :i stud; and Fig'. 5 is :i section on the line F3. being` partly in elevation.

l l'.teferrine` to the drawings and to the prev.terr-ed .torni ot my inrention selected for .l here shown a. stud illustrative pnrposes, which may be ot the usual torno including' n bend (i, neck 7 and bese 8 attached to the stud-cerrying 'fabric 9 in :my suitable Way :is by stitching througrlitbe stitchreceiving apertures 110. The preierred illustrated ot' tyi'ie adapted to be sewn to the cnrryineY .ielnici though types of socket adapted to be inetellicnlly securedto their fabrics may to advantage utilize ill, having a.

itself, as best shown in Fig. 5 Ato provide 'it bead 14; surrounding` the marginal` portion ot the stud-reciving aperture. This aperture greatly increases the strength ot the socket casing i'or any given grade ot' metal used .in its construction. ond, Whether or not the metal used for the socket is otl such gouge as to require reinforcement, the bend isA preterziblyprovided because it .increaises 'the smoothness of operation of the fastener when stud and socket are enga-ged and disengnged. particnlerly when under lateral strain. This smoothness ot' operation is pro- `vided not only because the thickness of the `'socket adjacent the portion thereof which bears on the stud When under lateral strain is increnserhdnit because smooth edge is provided. preferably rounded :is illustrated, sor that there is no tendency tor the inner ediqe of the socket surrounding the stud-receivjng; aperture 12 to dig into the neck oit the stud and unduly increase 't'rictionezl resistance to desired separa-tion `ot stud and socket when under lateral stra-in. llfhile the bead 11tis preferably provided by turning the edge ot' the metal inimrdly and back- `Wnrdly so that the projecting bend is on the inside `ofthe casino'. the bead may be formed in other Ways While retaining' many of the advantages produced by the construction illustrated.

Claims. n f

l. A socket for separable fasteners including teasing haring oplete with studreceivingz aperture tberetbroughj seid plate hei/inf n, return tlenge :it its migre adjacent the aperture.

2. The method ot' streneteiening the socket platte of o, separable testener which. comprises bending the plete :it its edge surrounding the stud-receiving aperture therein.

3. The method of strengthening the socket e, separable fastener which coniprises punching' the stud-receiving aperture thereinA proifiding o. tubular flange end en pending said flange outwardly to provide a bead doubling the thicknesses'of metal adje.- cent the aperture. y

4. l socket for seporable fasteners includ-A vSO ing a easing haring a plate `with a stud-re ceiving aperture therethrough, said pla-te being beaded at its edge adjacent the stud receiving aperture. u

5. Asoeket for separable fasteners including a 'easing having a plate with astud-receiving aperture therethrough, said plate beingheaded' at its edge adjacent the stud-re (serving aperture, the head lgn'ojeetinp; toward the inside face of the plate.

In 'testimony whereof, I have signed'niy naine to this specification.`
